Geologic structures

Type of structure Local
Structure description Thin, discontinuous veneers and lenses of gold-bearing jasperoid are exposed along a north-south volcanic/limestone contact for a strike length of 12,000 feet.

Ore body information

  • General form TABULAR

Controls for ore emplacement

  • Gold mineralization is erratically distributed throughout the jasperoid and is locally present in the volcanics, including a 30-foot zone averaging 0.036 ounces of gold per ton in one drill hole.

Comments on the geologic information

  • The New Pass project is a jasperoid-hosted gold system. Jasperoids, as thin, discontinuous veneers and lenses in limestone, are locally exposed along a north-south volcanic/limestone contact for a strike length of 12,000 feet. Drilling results indicate the jasperoids increase to 100 feet in thickness down dip and occasional silica flooding of the volcanics occurs at the volcanic/limestone contact.

Comments on the workings information

  • Recent work on the property consists of drilling and sampling. The historic New Pass Mine included in the current deposit was developed by the 550-foot Thomas W. shaft, the Gold Belt shaft, the Superior tunnel, numerous pits, cuts, adits, and several miles of underground workings.

Comments on other economic factors

  • Past production from the historic New Pass Mine near the southeast end of the claim block is estimated to have been 35,000 short tons of ore between 1868 and 1964. In 1998, the current New Pass deposit was estimated to contain 170,500 troy ounces of gold contained in 3.1 million short tons grading 0.055 oz. per ton.

Comments on development

  • Sporadic mining of vein deposits lying mainly east of this deposit produced 35,000 short tons ore between 1868 and 1964. Westmont Gold Inc. and its predecessors explored the New Pass area beginning in the early 1980s, and identified the current deposit in 1994. In 1997, Quest U.S.A. Resources Inc. controlled 100% of the project by virtue of its acquisition of Westmont in 1994. In 1997, White Knight Gold Inc, and Quest agreed to a mining venture wherein White Knight may earn a 51% interest in Quest's New Pass property by spending $1,500,000 over the next four years. Quest would retain a 49% participating interest in the property. According to the terms of the agreement, White Knight would make cash payments to Quest totaling $325,000 over a three-year period and pay the annual claim fees totaling $84,400 over four years. Drilling identified three exploration targets which include deep potential for Carlin style high grade gold mineralization; these require additional testing, In 1998, White Knight reported that a comprehensive review of all previously generated drilling and geological data provided new insight into the structural control of high-grade gold mineralization at New Pass. The company is currently seeking a joint venture partner to implement a 6,000 foot (12 hole) reverse circulation drill program designed to increase the known high grade resource. A Plan of Operations was submitted to the Bureau of Land Management for approval. New Pass is 100% owned by White Knight, subject to a 2.75% NSR payable to Quest U.S.A. Resources Inc.
